AUTOMATIC CUT-OUT FOR MAGNETO-GENER ATORS.

SPECIFICATION forming part of Letters Patent No. 610,023, dated August 30, 1898.

Application filed May 26, 1898. Serial No. 681,765. (No model.)

To aZZ whom it may concern.-

Be it known that we, WILLIAM J. BOWEN and CHARLES A. FEDEEER, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Automatic Out-Outs for Magneto-Generators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional elevation of one form of our improved cut-out, showing the connections diagrammatically. Fig. 2 is an end elevation of the cut-out. Fig. 3 is a vertical section of another form of our improved apparatus, and Fig. 4 is a sectional end elevation of the same.

Our invention relates to the cut-outs employed in connection with telephone systems, and is designed to simplify and improve the construction of such cut-outs, whether used in a series or multiple system.

Referring to the form of Figs. 1 and 2, 2 represents the shaft or spindle of the cut-out,

having at its outer end a suitable crankhandle 3, this shaft being mounted in bearings (not shown) at each end. Near one end a disk 4, of insulating material, is secured to the shaft by a setscrew 5 or other suitable means, and in the edge of this disk is provided a notch or recess which is faced upon one side with a plate 6, connected to an annular contact-ring 7, secured to the face of the disk and upon which ring presses the contact-finger 8. The other side of this recess is faced by a plate 9, secured by screw 10, which forms a binding-post for a conductor 11, which leads through the spindle and is joined to a conductor-pin 12, held in an end recess of the spindle by a surrounding sleeve 13 of insulating material. The disk 4 may be made in the form of an arm or any other desirable shape than the complete disk shown, and we intend to cover the same by the word projection, as used in the claims.

14 is a contact-plate, one finger of which presses upon the end of the pin 12, while the other finger presses upon a similar pin 15, held in a similar recess in the end of a spindle 1G, with a surrounding sleeve 17 of insulating material. The spindle 16 forms the armature-shaft of a magneto-generator 18, this shaft having a pinion 19, which engages with the toothed wheel 20, loosely mounted upon the spindle 2. The wheel 20 is provided with a projecting pin 21, of conducting material, which rests within the recess or notch in the disk &, and the disk is normally held so that the plate 9 will contact with this pin by means of a spiral spring 22, secured to the disk and to the toothed wheel. In this form we have shown the cut-out as applied to a multiple system of telephone-bells, a and I) being the lines of the circuit, 0 being the circuit from the magneto-generator to the line, and (Z the circuit connecting the body of the generator to the line through the contact-finger 8 and the pin upon the loose wheel.

23 is'the ringer, and 2a the telephone-receiver, hung upon the hook 25, which conneets the bell-circuit in the usual manner.

hen the bells are to be rung, upon turning the crank of the generator the disk 4 will be swung to break the contact between 21 and plate 9, and contact will be made between this pin and the plate (3. The armature-shunt is therefore automatically opened and the circuit closed or completed across from one side of the line to the other through the armature, thus placing the same in multiple with the ringer and with the other bells upon the line. The current generated in the armature will thus pass to the line and divide up and actuate all the ringers on the circuit. As soon as the handle or crank is released the spring will automatically throw the pin upon the loose wheel into contact with the plate 9, thus short-circuiting the armature independent of the line.

In Figs. 8 and a we show another form of our improved cut-out arranged for a series system. In this form the spindle 2 is made short and supported in a single bearing 26. The parts of the cut-out are otherwise substantially the same as those shown in Figs. 1 and 2, and we have accordingly marked them with similar numerals bearing the prime mark. As this form is arranged for a series system, I omit one of the facing-plates at one side of the notch in the insulating-disk, together with its conductin ring or finger, the other facing-plate 9 being connected through the spindle in the same manner as before. This generator is normally in a shunt from the line-circuit around the armature-coils,and when the crank is actuated the action is the same as above described in relation to Figs. 1 and 2, the armature-current passing out on the line.

The advantages of our invention result from the simple and effective construction of the cut-out apparatus.

We claim 1. In an automatic cut-out, a rotatory spindle having a projection of insulating material provided with a recess, a loosely-mounted Wheel connected with the generator and having a pin resting Within the recess of the projection, a contact-plate secured in the recess and a spring arranged to normally hold the plate and pin in contact; substantially as described.

2. In an automatic cut-out, a spindle carrying a loose wheel and an insulating projection rigidly secured to the spindle, a pin-and-slot connection between the wheel and projection, a contact-plate on one of these parts, and a spring arranged to hold the pin in contact With the plate; substantially as described.

3. In an automatic cut-out, a spindle having a loose wheel mounted thereon, and connected to the magneto-generator, a disk of insulating material secured to the spindle, said disk having a notch engaged by a conductingpin upon the Wheel, a contact-plate within the notch, a connection leading from the contact-plate through the spindle to the ma neto-generator, and a spring arranged to hold the plate in contact with the pin; substantially as described.

4. In an automatic cut-out, a spindle having a loose Wheel mounted thereon and connected to the magneto-generator, a disk rigidly secured to the spindle and having a recess engaged by a conductor-pin on the Wheel, a contact-plate within the recess connected to line, another contact-plate Within the recess connected through the spindle to the magneto generator, and a spring connected to the disk and the Wheel to hold the pin normally in contact With the plate connected to the generator; substantially as described.

In testimony whereof We have hereunto set our hands.
